Rinse 1 cup of quinoa thoroughly and soak it in water for 4-5 hours.
Drain the soaked quinoa and transfer it to a mixer or grinder.
Add 1/2 cup of rice flour, 1/4 cup of urad dal (soaked for 4-5 hours and drained), and 1/4 cup of poha (flattened rice) to the mixer.
Grind the mixture into a smooth batter by adding water as needed. The consistency should be similar to regular dosa batter.
Transfer the batter to a large bowl and add salt to taste. Mix well and let it ferment for 6-8 hours or overnight.
After fermentation, mix the batter well and adjust the consistency by adding water if required.
Heat a non-stick tawa or dosa pan on medium flame. Pour a ladleful of batter onto the tawa and spread it evenly in a circular motion to form a thin dosa.
Drizzle a few drops of oil around the edges of the dosa and cook until the bottom turns golden brown.
Flip the dosa and cook the other side for a minute.
Serve the quinoa dosa hot with coconut chutney, sambar, or any other accompaniment of your choice.
